Explosion proof on off switch , anti - corrosive push button switch
Description:
The explosion proof on off switch,also known as push button switch, is a low-voltage electrical appliance that is manually and generally can be automatically reset. The button is usually used to issue a start or stop command in the circuit to control the on and off of the electrical coil current of the electromagnetic starter, contactor, relay, and the like.
The push button switch is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in control circuits with AC/DC voltage below 440V and current less than 5A, generally do not directly manipulate the main circuit, and can also be used in interconnect circuits.
In actual use, in order to prevent misoperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like. Normal red means "stop" or "dangerous" operation; green means "start" or "on".

With key type; anti-corrosion type should be used in the case of corrosive gas.
(2) Select the color of the button and indicator according to the working status, the requirements of the instructions and the working conditions: the green color for the "start" or "power on", the voltage of the red indicator light (light bulb) indicating "stop" Divided into 6.3V, 12V, 24V and so on.
(3) According to the needs of the control loop, determine the number of different buttons: such as single button, double button, three button, multi button, etc. For example, when you need "positive", "reverse", "stop" three controls, three can be used. Buttons, and are installed in the same button box; when only "start" and "stop" controls are used, they are assembled in the same button box with two buttons
